Ansys workbench计算报错
做ANSYS热电耦合计算时，网格数少一点还可以算，增加到100万左右就算不了了，是服务器内存不够吗？/COM,ANSYS RELEASE Release 18.0 BUILD 18.0 UP20161219 10:55:14
*** WARNING *** CP = 181.844 TIME= 10:55:48
Element shape checking is currently inactive.Issue SHPP,ON or
SHPP,WARN to reactivate, if desired.
*** WARNING *** CP = 311.531 TIME= 10:56:38
Contact element 1104226 is missing DOF VOLT (and possibly others) of
underlying base element 676.Similar mismatches may exist elsewhere,
but checking for this is discontinued.
*** WARNING *** CP = 320.969 TIME= 10:56:48
Minimum contact depth 4.998002316E-06 is too small which can cause an
accuracy problem, you may scale the length units in the model.
*** WARNING *** CP = 901.672 TIME= 10:57:57
Coefficient ratio exceeds 1.0e8 - Check results.
*** WARNING *** CP = 1180.781 TIME= 11:02:04
The Sparse Matrix Solver is currently running in the out-of-core memory
mode.This memory mode may provide significantly worse performance
compared to the in-core memory mode, depending on the amount of
available system memory and I/O speed.Please monitor the solver
performance to ensure that the large amount of I/O to the solver files
does not create a bottleneck for performance.
*** ERROR *** CP = 88180.141 TIME= 12:24:21
An error has occurred in the Sparse Matrix Solver while factoring the
matrix.Error code = 18.Please send the data leading to this
operation to your technical support provider, as this will allow
ANSYS, Inc to improve the program.
*** WARNING *** CP = 88184.844 TIME= 12:24:26
During this session the elapsed time exceeds the CPU time by 508%.
Often this indicates either a lack of physical memory (RAM) required
to efficiently handle this simulation or it indicates a particularly
slow hard drive configuration.This simulation can be expected to run
faster on identical hardware if additional RAM or a faster hard drive
configuration is made available.For more details, please see the
ANSYS Performance Guide which is part of the ANSYS Help system.
*** WARNING *** CP = 88184.844 TIME= 12:24:26
During this session a solution was performed using 20 CPU cores in
shared-memory parallel (SMP) mode (-np 20).It is strongly
recommended to use distributed memory parallel (DMP) mode instead
(-dis -np 20).DMP mode typically outperforms SMP mode, even when
running on a single system.For more information, see the ANSYS
Parallel Processing Guide in the ANSYS Help system.
很可能是内存不够。将求解器改为迭代求解试试。否则就需要加大内存或减小模型规模。
